Of course it should not hinder the UX of copy pasting in the process. I probably hate that just as much as you.

> I almost never want to use a number as a phone number.

This is the 'what you want and what you need'. You don't want to copy and paste a number into a phone to dial them. You need to have a voice call with the person/company who's page you are visiting or email you are reading.

Google search solves this nicely in their mobile search. They don't show phone numbers or addresses primarely, but buttons to like Call, Navigate, Share and Website. That is what I need when I search a company on Google and essentially what I want.

How about if you could change the context menu in the settings. If you want dial, check that you want dial in the settings, if never use dial, check off in settings.
